For all its resiliency and creativity, the human brain is equally fragile and prone to disease. Millions around the world are affected by neurological and neurodegenerative diseases. In fact, a World Health Organization study found eight out of 10 disorders in the three highest disability classes are linked to neurological problems, a figure likely to increase, as the global elderly...
Casey Ankeny has taught almost 2,500 students in 28 classes — in multiple versions of five different courses — since joining the faculty of Arizona State University’s Ira A. Fulton Schools of Engineering as a lecturer only four years ago. Often about 100-plus students have been in those classes, which all together cover subject matter spanning nearly the entire range...
Arizona State University has earned six prestigious U.S. Department of Energy SunShot Awards, totaling $4.3 million, ranking it first among recipients in the Photovoltaics Research category for 2017. This year’s awards, which come with grants totaling $20.5 million overall for 28 projects, supports the development of new commercial photovoltaics technologies that improve product performance, reliability and manufacturability. In this round,...
U.S. Secretary of State Rex Tillerson has seen a chance for progress in the conflict in Ukraine and has tapped Kurt Volker, executive director of the McCain Institute for International Leadership, a unit of Arizona State University, to work with both sides in the peace process. Kurt Volker Volker was named a special representative for Ukraine negotiations on July 7...
From Italy to Iceland to Indonesia, volcanoes have been worshipped and venerated for centuries, seen as the abode of angry and capricious gods mollified only by fish, pigs, and holy relics. It’s human nature to ascribe divinity to mysterious natural processes, and to want to make them go away with a chicken or a lock of hair. No one, even...
Six million American households rely on propane gas to heat their homes and water, dry their clothes and barbeque their pork chops. Farmers use propane to heat livestock housing and greenhouses, dry crops and power farm equipment and irrigation pumps. Many businesses employ propane to power equipment ranging from forklifts to electric welders. Transporting this fuel to homes and establishments...
An important contributor to the efficiency in Photosystem II is mediation of charge separation by a tyrosine residue (Tyrz). Oxidation of Tyrz as part of the charge separation process occurs in concert with transfer of a proton from the oxidized tyrosine to a neighboring histidine (His) residue. This concerted electron-proton transfer not only promotes charge separation, but also generates a...
Every year it seems like we have another device to charge — laptops, smartphones, tablets, wearable electronics, electric cars and so on. Charging processes ubiquitously use power electronic switches to convert electricity from one form to another so that it can be used in these devices. As power electronics become increasingly part of how we move and consume electricity, the...
There’s an exciting change under way in the scientific community. Citizens with an avid interest in science are getting the chance to contribute to real research through data collection and analysis in collaboration with professional scientists. These “citizen scientists” — tinkerers and enthusiasts of all stripes — are being given the tools and platforms to turn their interests into real...
